Hi community, I want to calculate the **average sleeping time** of the past week with a Logic calculation. I don’t know how. I looked through topics, Google and I asked ChatGPT. ![1000031015](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/2/82fa470e6266cc0e2d63a92793cc165be1fe8d02.jpeg) Is there any one who can point me in the right direction? Thanks Rogier ---

Hi Rogier, This is a way to calculate it. I use the Better Logic time formatting card to convert the counted stopwatch seconds to an H:mm format ![1000001140](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/1/7152cda2917ce06bc7a2e46f5e577bfbf2c2c38f.jpeg) > ![1000001135](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/b/bbf72a9ebf8cd850a780f9dc8bd79ddd094c3f13.jpeg) ---

We have our phone the the bedroom (I know not a “smart” thing to do, and not everybody agrees). I have the phone charger linked to a power measuring switch. We ge sleep, phone is in the charger → sleeping. in the morning, check if charger goes to 0 (0.5w is standby) → awake. Maybe an easy alternative [Previous page](https://community.homey.app/t/calculation-of-variables-logic-or-better-logic/39913.md?page=2)
